Hey community,

I want to present you my new intuitive calculator: One++
(once Easy4Me)

It's very easy:
Choose the function you need, enter the variables and One++ calculates everything you want to know.
Example 1: Enter the side length of an cuboid and One++ tells you the surface area, the volume, the diagonal length and some more.
Example 2: Enter a valid range of numbers and he will tell you the primes, twin-primes or something else you want to know within this range.

Main features:

★ 7 categories: all, favourites, everyday, math, converter, physics, economics
★ 243 menu points / functions: Every class with some variables that can be calculated
★ 1000+ variables and formulas
★ 5 Material themes: dark, light, black, translucent, grey
★ 15 scroll-animations: push left in, push right in, push down in, push up in, push forwards in, wave, fade in, rotate (in and out), random
★ 7 designs / layouts: Icons, Pattern, Tiles, Simplistic, Simplistic cards, Simplistic Icons, Simplistic Tiles
★ 12 languages: German, English, Spanish, Italian, Polish, Russian, French, Indonesian, Portuguese, Chinese, Croatian, Turkish
★ Text to Speech for the results
★ Xposed module: InApp DPI settings (experimental)
★ Statistics: To see your usage of this app.
★ Floating action menu: Link up to 4 of your favourite apps with One++ to get quick access to them.
★ Snackbar: To show tips.
★ A lot more

Suggestion to add: in physics, you have inductance, but no capacitance or impedance or phase angle. Could you add that?

Sent from my One M8 using Tapatalk
Yes I will do so. At the moment I'm optimizing the whole code and adding some 3D animations for the buttons and other UI elements. That will take a few days. Than I will add these functions :)
If you have more ideas, please tell me. I will add them soon ;)
Thank you for useful app!
Great to hear, thanks for your reply :)

Polish language?

Wysłane z mojego JY-S3
Hey I'm planning to integrate some more languages (Polish, Spanish, French and some more), but for the moment I've no translators (and I don't speak these languages). So maybe if you know someone who can help me by translating the app, please contact me :) I'm working on it ;)
This is an amazing app. Thank you so much!
Thank you very much! I'm glad you like it :)
